@Greg *******
do you understand how tax law works?
If you live here, that’s resident for more than 6 months, you are liable for declaring tax on ALL income.
But most countries will have a double taxation agreement with Thailand so you would technically only be liable for the difference.
The problem that will come is they can see how much money you bring into the country, and if you don’t file a return then you will probably have issues at some point. Might not be for a while but it could be a problem in the future.
No different to anywhere else. You would be good to take advice on this if trading anyway and not resident anywhere else. There could also be benefits to setting up as a business in 3rd country to minimise the tax liability.
What you shouldn’t do though is think because I make money elsewhere that it’s nothing to do with me living here. Because it most certainly is.
Oh and if you are talking about the DTV and how that will work when everyone works remotely, it will be exactly the same. People will get caught out if they don’t prepare and understand this.
Also consider if you are here on any type of visa that doesn’t allow work, remote work will be breaching immigration law which would possibly lead to deportation.
All I’m trying to say is, don’t bury your head because others do. People get caught, kicked out, and all sorts all the time here and you’ll never hear about it.
Currently over 1000 people a week being rejected entry just in the 2 airports in BKK. Because tourist visas and bounces have been abused.
